Stack Tower Insanity

How high can you stack before the tower fights back? Stack Tower Insanity starts as the stacking game you know — tap to drop blocks, land them perfectly to keep your tower wide — and turns into something else entirely the higher you climb. * STACK Tap to drop moving blocks. Perfect drops keep your block wide and build combos. Miss the edge and your tower shrinks until there's nothing left to land on. * SURVIVE THE SWAY From floor 50 the whole tower starts swaying. Timing gets harder, drops get riskier, and every perfect landing matters. * FIGHT BACK Reach floor 100 and the game transforms: your block becomes a ship. Steer with tilt controls, auto-fire at incoming enemies, and survive as long as you can. Every floor past 100 is earned in combat. * UPGRADE YOUR SHIP Spend coins on fire rate, damage, and hull upgrades to push deeper into combat mode. * CLIMB THE LEADERBOARD Compete globally with your own profile — pick a name, an avatar, and a frame, and see exactly who you need to beat. * 36 ACHIEVEMENTS From your first perfect drop to one million blocks stacked. Game Center achievements included. * MAKE IT YOURS Unlock tower skins, backgrounds, avatars, and profile frames with coins you earn by playing. Free to play. Optional in-app purchases (coin packs, cosmetic packs, remove ads, 2× rewards) and ads that can be removed forever with a single purchase. Simple to learn. Brutal to master. Insane past floor 100.
